Open Book Test

The Oklahoma Plumbing Contractor and Natural Gas technical examination and the applicable Plumbing Business and Law examination are open-book tests. Candidates may use approved reference materials according to the examination provider's rules.

Approved references may be highlighted, underlined, and indexed before the examination. Permanent tabs may be used to organize the materials. Temporary tabs such as Post-it notes are not permitted.

The open-book format makes reference navigation an important part of preparation. Candidates should learn which reference applies to each subject and practice locating information efficiently before test day.

For example, plumbing system questions may require the International Plumbing Code, while fuel gas questions may involve the International Fuel Gas Code. Construction safety topics may require OSHA 29 CFR Part 1926, and mathematical questions can involve Mathematics for Plumbers and Pipefitters.

Business and Law questions may require the Oklahoma licensing statutes and regulations, lien law, fine schedule, or NASCLA Contractors Guide. Practicing with each reference helps candidates develop a more efficient approach to locating information during an open-book exam.

State Requirements

Oklahoma plumbing contractor applicants must meet the same qualification requirements applicable to plumbing journeymen and complete an additional one year of lawful plumbing trade experience.

Applicants must complete the applicable Oklahoma licensing application and receive examination approval before scheduling the required tests. Contractor applicants are required to complete the plumbing examination and the Plumbing Business and Law examination.

After the required examinations are successfully completed, an Oklahoma contractor license remains inactive until the Construction Industries Board receives the required bond and insurance documentation.

An active Oklahoma plumbing contractor is required to maintain a $5,000 corporate surety bond payable to the Oklahoma Construction Industries Board. The bond must meet applicable state requirements and be maintained while the contractor remains active.

An active plumbing contractor must also provide evidence of at least $50,000 in commercial general liability insurance. Maintaining current insurance is an ongoing responsibility for active contractor status.

Oklahoma plumbing contractors must also comply with applicable requirements involving apprentice supervision, license display, advertising, contracts, bids, continuing education, and other responsibilities established for licensed contractors.

Journeymen and contractors are currently required to complete six hours of approved continuing education within the 36 months preceding license expiration.

Test Information and Study Materials

A strong preparation plan should cover both the technical examination and the Business and Law examination. For the technical test, give substantial attention to vents, water supply, drains and sewers, general plumbing knowledge, and fuel gas. These represent significant areas of the examination.

Use the International Plumbing Code to practice locating requirements involving fixtures, water distribution, backflow protection, drainage, building sewers, cleanouts, traps, interceptors, venting, and piping materials.

Use the International Fuel Gas Code to review gas piping sizing, regulators, supports, joints, valves, appliances, combustion air, testing, inspection, and venting. Rather than trying to memorize every table, practice locating and applying the correct sizing information.

Isometric analysis and plumbing calculations should also receive dedicated preparation. Mathematics for Plumbers and Pipefitters can support review of measurements and numerical concepts used in plumbing applications.

Construction safety preparation should include OSHA requirements involving personal protective equipment, excavations, ladders, scaffolds, fall protection, tools, material handling, and other common jobsite hazards.

For Business and Law, organize study around bidding and estimating, project management, contracts, financial management, labor, risk management, payroll, taxes, liens, and Oklahoma licensing requirements. Practice connecting each topic to the appropriate reference so lookups become faster and more purposeful.

The 1 Package combines this exam preparation with licensing and business setup support, allowing candidates to approach the process as a connected path rather than separate tasks.
